The experiment indicated that the seeds were soaked in chitosan of feasible concentration, the germination ratio of the seeds, the growing state and the stress-resistance of the seedlings could be improved and the turf establishment time could be shorted.Keywords : Chitosan Dichondra repens Forst. Germination Activities of Enzyme

试验说明，用适量浓度的壳聚糖溶液对马蹄金浸种，可以提高种子的发芽率，改善苗期的生长状况，提高幼苗的抗逆性，缩短成坪时间。

The results showed that allelochemicals of all 10 kinds of donor species have allelopathy on seed germination of Eupatorium adenophorum, and allelopathy increased with the enhancing of concentration.

结果表明：10种供体植物的化感物质对紫茎泽兰种子萌发均存在化感作用，并且随着浓度的升高，化感作用逐步增强，紫茎泽兰种子发芽速度指数比发芽率更为敏感。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.
